Hello there.
I can understand your concern. Toothache can be very irritating.
You can take a pain killer as of now. A combination of aceclofenac and paracetamol will be enough for now. But mere pain killer won't be enough.
The cause of the toothache needs to be evaluated and then the cause will need to be treated.
Do salt water gargles and brush your teeth twice a day.
Consult a dentist for determination of the cause and then get the cause treated.
Best regards.
